A car with a mass of 1,300 kg travels a distance of 200 m as it moves from one stoplight to the next. At its fastest, the car travels at 20 m/s. What is its
kinetic energy at this point?
O A. 260,000 J
OB. 520,000 J
O C. 13,000 J
O D. 2,600 J

Avalue that describes how heavy an object is and is related to the force of gravity is

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
